REYES RODRIGUEZ, Maida Bárbara; MOYA RODRIGUEZ, Jorge Laureano  y  CRUZ FONTICIELLA, Oscar Miguel. Ecological impact of Shell and tube heat exchangers. Energética [online]. 2015, vol.36, n.1, pp. 104-112. ISSN 1815-5901.

Shell and tube heat exchangers are ones the most important equipment in the industry. Their thermodynamic design is based on the global heat transference coefficient and the pressure drop. In 2007 was settled a new thermodynamic property denominated "Entransy", which expresses the capacity of a body to transfer heat. The loss of this capacity is denominated "Entransy Dissipation". For evaluating the ecological impact of thermal machines, Angulo-Brown created in 1991 the "ecological function". In this paper the"entransy dissipation" and the ecological function were combined and a new expression for evaluating the ecological impact of shell and tube heat exchangers was created. A multi-objective optimization of this equipment wasalso realized. The ecological function and the cost wereused as objective functions. For carry out the optimization the method of the Genetic Algorithms was used.

Palabras clave : genetic algorithms; entransy; ecological function; heat exchangers; optimization.
